‘Electronic Tattoo’ Measures Nerve, Muscle Activity

Researchers at Tel Aviv University have developed a temporary “electronic tattoo” that can be placed on the skin and used to measure and record nerve and muscle activity. The electrode was initially designed as an alternative to electromyography (EMG)—a medical test used to evaluate muscle and nerve function and diagnose neurodegenerative conditions. Using this new technology, patients would be able to go about their daily activities while the test is being conducted.

The device consists of an electrode, an adhesive surface that attaches it to the skin, and a nanotechnology-based conductive polymer coating that improves the performance of the electrode. Interestingly, signals received from the facial muscles can help researchers identify and map the patient’s emotions—an additional application of the device.

According to researchers, this new technology may have other applications as well. For example, it may be used to measure alertness in drivers and to aid in rehabilitation following a stroke or traumatic brain injury.
